About Chalcopyrite
Chalcopyrite is a captivating mineral sought after by collectors for its dazzling metallic luster and distinctive brassy gold coloration.  It forms in a variety of crystal habits, from granular masses to distinct tetrahedral or dodecahedral crystals, often exhibiting iridescent hues of purple, blue, and green, caused by surface oxidation.  This mineral is a significant source of copper ore and is commonly found in hydrothermal veins alongside other sulfide minerals such as pyrite and sphalerite.  In fact, we often refer to it as pyrite with a copper molecule added.  They are commonly mistaken for each other and can be difficult to distinguish when they are found in geologic occurrences together.
